If you have a new generation Samsung T-Mobile phone that was manufactured after October 2014 you can try it with this tool. If the code comes back as “NOT FOUND" we cannot do anything about it, just try another tool.

- IMEIs starting with 9900 and Verizon Devices*- Any Samsung Cell Phone from T-Mobile USA with "Mobile Unlock App" installed and that are not asking for SIM Network Unlock PIN (like some Galaxy Avant, Galaxy 6 Edge, and probably more to come in future...)
